Which statement about NAUI RGBM dive tables is true?

Which statement about NAUI RGBM dive tables is true?

• A. They are for air only
• B. They are for air and nitrox and can be used for elevations up to 3048 m
• C. They require a computer to use
• D. They guarantee zero DCS risk

Answer: (B)

NAUI RGBM dive tables are designed for planning dives using air or enriched air nitrox, and they include altitude corrections so they can be used at elevations up to about 3048 meters (10,000 feet). That combination—supporting both air and nitrox and providing altitude adjustments—makes this statement true. You don’t need a computer to use them; they’re tabulated for manual reference, though a dive computer can be used as an alternative. They do not guarantee zero DCS risk—no set of tables can eliminate risk entirely, only manage and reduce it.
